Abstract

CHAILE, Cecilia et al. Análisis de residuos orgánicos en tecnología cerámica durante el Holoceno tardío en el centro-oeste de Santa Cruz, Argentina. Intersecciones antropol. [online]. 2018, vol.19, n.2, pp.133-143. ISSN 1850-373X.

In this paper the results of a study of the use of pottery technology by hunter-gatherers from central-west Santa Cruz, Argentina, towards the end of the Late Holocene are presented. The results of C and N stable isotope (EA-IRMS) and chemical (GC-MS) analyses of organic residues recovered from archaeological sherds are reported. Stable isotope data indicates that the origin of the adhered organic residues is from steppe animals. In addition, the fatty acid profiles of the archaeological samples were very similar to guanaco (Lama guanicoe), particularly linear and branched odd fatty acids, which are potential lipid biomarkers of ruminants and pseudo-ruminants. Most samples had cholesterol. None showed vegetable oils in the absorbed lipid residues. Hence, the archaeometrical evidence points towards the use of pottery for the extraction of guanaco fat by hunter-gatherer groups of central-west Santa Cruz.
